| IL-24 is a [[cytokine]] belonging to the [[Interleukin 10|IL-10]] family of cytokines that signals through two [[heterodimer]]ic receptors: IL-20R1/IL-20R2 and IL-22R1/IL-20R2. This interleukin is also known as melanoma differentiation-associated 7 ('''mda-7''') due to its discovery as a [[tumour]] suppressing protein. IL-24 appears to control in cell survival and [[cell growth|proliferation]] by inducing rapid activation of particular [[transcription factor]]s called [[STAT1]] and [[STAT3]]. This cytokine is predominantly released by activated [[monocyte]]s, [[macrophages]] and [[helper T cells|T helper 2]] (Th2) cells<ref name="pmid16000394">{{cite journal |vauthors=Poindexter NJ, Walch ET, Chada S, Grimm EA | title = Cytokine induction of interleukin-24 in human peripheral blood mononuclear cells | journal = J.
